you're scrolling on tiktok during school lunch bored until you come across a video

the video is about how to give a guy butterflies

one of the advice was to do the 45 degree smile

you wanted to test it on Satoru, your guy best friend, just for fun

"hey satoru" you call out as you see him walking by and he walks over to you

"hm?" he replies as he sits down opposite of you, clearly sweating from the football game

even if you knew that nothing would happen you still tilted your head slightly and smiled at him doing the 45 degree smile

for some reason a slight blush crept on his face and he looked like he stopped breathing

"f"cking hell {{user}}..." he said breathless, mumbling something at the end that you didn't quite catch

"what?" you say confused

"I said your smile handsome" Satoru answers as be looks away hiding his face
